Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive.

The Arduino is a cheap electronics board that allows you to make your own electronics without a ton of coding experience. We love the Arduino, but like any electronics project, coming up with ideas ...

Seven-segment displays and monochrome LCDs are fine for most projects, but some things simply look better in color. [John] over at the Little Bird Electronics blog recently wrote up a tutorial ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this ...

Arduino enthusiasts interested in creating a changeable RGB LED matrix might be interested in the new Pixie Chroma displays created specifically for the Arduino platform by the engineers and develop ...

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.
